Does Humana Gold Plus Cover Mounjaro? Medicare Advantage Coverage Guide 2026
Medicare Advantage enrollees with Gold Plus HMO (from Humana) frequently want to know whether Humana Gold Plus covers Mounjaro (tirzepatide). In brief: coverage varies by several plan-specific factors.
Humana Gold Plus’s Formulary Position on Mounjaro
Gold Plus HMO operates with a drug formulary that categorizes medications into cost-sharing tiers. For the 2026 plan year, Mounjaro is generally classified as Tier 4 (Non-preferred specialty) for typical Humana Gold Plus plan designs.
What this means for you:
- Monthly copay: $100–$300+ depending on coverage phase
- Prior authorization: Required — a PA request is needed
- Quantity limits: May apply — limited to FDA-recommended dosing
- Step therapy: Could demand trying metformin, insulin, or other treatments first
In the donut hole phase, cost-sharing increases to 25% coinsurance before catastrophic coverage applies.
Coverage for FDA-Approved vs. Off-Label Use
For type 2 diabetes (FDA-approved):
- Humana Gold Plus is more likely to approve Mounjaro with appropriate documentation
- Required evidence: clinical records showing medical necessity
- Approval rates are higher when used on-label
For weight loss (if seeking obesity coverage):
- CMS policy generally prohibits anti-obesity medications for weight loss alone
- An exception exists: 2025 policy changes expanded Part D coverage eligibility for weight management medications
- Humana Gold Plus may offer enhanced coverage that cover weight management medications — call Humana member services
